The high availability of information provided through standards typical of the Web 2.0 world (e.g. RSS feed, atom, etc.) and services exposed by means of Web service API (see [1] for a list of more than 1300 APIs) leads to the development of new tools for the rapid creation of applications-called mashups-that combine these different sources. More specifically we refer to the event driven class of mashups, in which a set of autonomous service components interact with each other under the control of an orchestrator. These autonomous service components may belong both to the Internet world (e.g. e-mail, RSS Feed, etc.) and to the Telco world (e.g. voice call, SMS, etc.). In this paper we discuss the requirements that should be fulfilled by a platform that supports the execution of event driven mashups. We consider performance issues such as low latency/high throughput as well as security and management issues such as AAA (authentication, authorization and accounting) and SLA (service level agreement) issues. Starting from these requirements, we propose a set of five design solution that allows to implement a scalable system for the execution of mashups. In particular, we describe the concept of session less orchestration that allows to fulfill the scalability requirement through a mechanism that frees the central engine from the burden of managing and storing session information. Finally we report the results of the evaluation tests performed on the platform prototype.
